Company Profile
Runh Power Corporation Limited was founded in 1996 as one of the earliest independent EPC contractor of power plant and later incorporated one of the most famous turbine designer and manufacturer, Qingdao ChuangNeng Steam Turbine Co.,Ltd (better known as CNT in China). With subordinate design institute founded in 2001, Runh Power was bestowed upon the capability of providing one-step, package technical solution of thermal, hydraulic, solar, biomass power plant.
Scope of service includes :
A. EPC (Engineering, Purchase & Construction) project of power plant plus financing service.
Power plant project on EPC basis (or "on turnkey basis") is characterized by the overall package solution provided by the contractor. Runh Power's service covers survey all the way till final acceptance.
